Research on optimization of conductivity of multilevel fractures in tight sandstone based on similar circuit principle

Energy Science &Engineering, Volume 12, Issue 6, Page 2627-2642, June 2024.
The post‐pressure fracture network is equivalent to a high‐permeability zone, and the reservoir numerical model is established to optimize the equivalent hydraulic conductivity of the fracture network. Based on the discrete element theory, the fracture expansion and its geometric parameters after volume fracturing of dense sandstone are simulated, and ...

Long‐term fracture conductivity in tight reservoirs

Energy Science &Engineering, Volume 12, Issue 3, Page 1187-1199, March 2024.
The fracture conductivity decreases with the increase of displacement time under the displacement of formation water and fracturing fluid, and the decrease of fracture conductivity under the displacement of fracturing fluid with time is greater than that of formation water displacement. The conductivity increases with the increase of sand concentration,

An Innovative Production Prediction Model for Fractured Horizontal Wells in Low‐Permeability Gas Reservoirs Accounting for Proppant Embedment

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
This study focuses on addressing the challenge of accurately calculating the production caused by stress sensitivity and proppant embedment during actual production in low‐permeability gas reservoirs. To achieve this, a stress sensitivity model in the matrix zone and a proppant embedding model in the fracture area are established.
